Post-Apocalypse

During the onset of the outbreak, Sheila and her partner Deborah fell in with the Archer Creek dam group after surviving a brutal attack on the way to Atlanta. Shelia joined the Dam's scavenger team under Kevin Hollis.

She is later found by Daryl Dixon at ClaraChem Labs. She is found trapped inside one of the lab stations and asks Daryl to free her, Daryl does so by activating the facility's hazard lockdown. After they both escape, she offers to join Daryl's group.

If Sheila reaches Firesign Stadium, she and another survivor will board the last evacuation helicopter. When Merle informs Daryl that the helicopter pilot was bitten, Daryl tries to tell Sheila but the helicopter takes off. Leaving Shelia's fate unknown.

Death

Killed By

Sheila along with any other survivor that may survive till the evacuation in Georgia, most likely died in a Helicopter Crash. As Merle notices that the "Whirlybird Pilot" had been bitten, and said he was already looking like he was going to turn. So the pilot might have turned mid-flight causing a crash, possibly killing Sheila and the other passengers.
